Case 49 year old female with history of Hodgkin’s lymphoma, breast cancer and valvular heart disease with CHF presents with epigastric pain S/p splenectomy and XRT 1977 S/p cholecystectomy 1990 S/p Mastectomy, XRT and chemo 1998 S/p pacemaker 2002 Meds: Furosamide Losartan Spironolactone ASA Tamoxifen
4/28: PE visit ROS: “stomach pain”, intermittent, worse after eating, better lying down, in past responded to ranitidine. Treated with ranitidine 150 bid 5/7: took ranitidine 3 days- side effects so stopped, epigastric pain better 6/7: pain recurred treated with Prilosec Called 2 weeks later and pain resolved
7/2: Epigastric pain worse, some nausea Prilosec increased to bid 8/27: Had quit all caffeine, off Prilosec and no pain 9/14: 24 hours of epigastric pain after onion rings, cheese burger and a beer on 9/5 now intermittent pain occ radiates to back no nausea/vomiting/ diarrhea

ERCP requested - done October 4 CBD - medium sized filling defects Sphincterotomy performed: several soft yellow stones and stone material removed Cholangiogram: no residual filling defects
Objectives Common bile duct stones: • Detection • Incidence • Etiology • Risks • Treatment
CBD Stones • Concomitant gallbladder and CBD stones • Post cholecystectomy CBD stones • Retained • Recurrent
Suspect CBD stones • Classic obstructive symptoms • fever, RUQ pain, jaundice • Recurrent symptoms after cholecystectomy • Pancreatitis
Suspect CBD stones • Hepatic biochemical tests • increased bili (> 2mg) • alk phosphatase (>150) • transaminases (2X normal) • RUQ ultrasound or CT scan • dilated CBD
Detection of CBD stones • RUQ ultrasound (sens 18-74%) • CT scan (sensi 76-90%) • IV cholangiography • Intraoperative cholangiography • Intraoperative CBD exploration
Detection of CBD stones • ERCP(Endoscopic retrograde cholangiography) • Gold standard for detection and exclusion of CBD stones • Diagnostic and therapeutic • Failure to cannulate about 5 % • Serious Risks about 5 %: • Pancreatitis, perforation, cholangitis, bleeding, sepsis, death
ERCP • Single small bile duct stone with sphincterotome in position. • (B) Clear bile duct after sphincterotomy and stone extraction.
Detection of CBD stones • MRCP (Magnetic resonance cholangiopancreatography) • Non-invasive • Detect stones as small as 2 mm • Sens 90-100% and spec 92-100% are close to ERCP • Useful to exclude CBD stones and avoid ERCP or an intraoperative evaluation of CBD Gastrointest Endosc 56(6 suppl); S178-82, 2002
MRCP Patient with abdominal pain and elevated alkaline phosphatase. ARROW = 1.4 cm, well-defined, low-signal intensity stone in the dilated distal common bile duct. ARROWHEAD = The normal-caliber pancreatic duct.
Study (Surg Lap Endosc 8:349, 1998 ) 316 patients having laparoscopic cholecystectomy 63 patients had increased bili, alk phos or GGT or dilated CBD on US and had ERCP 12 (3.8 %) had CBD stone
Study (continued) 3 year f/u of 253 patients: 6 (2.3%) had retained CBD stone 4/4 with symptoms – jaundice/biliary colic/abn labs 2/4 with abn labs but asx
Incidence of CBD stones At time of cholecystectomy: 2.5 – 10 % (mean 6 %) Undetected retained CBD stones: 1-3 % over 3 years Recurrence of CBD stones: 24% over 15-17 years Surg Lap Endosc 8:349, 1998 Gastrointest Endosc 44:643, 1996
Why do CBD stones form? • Passed into CBD from gallbladder • Form in the CBD: • Bacteria in biliary tree and stasis promote stone formation • ERCP may increase bacterial contamination but should decrease stasis
Risks of Common Bile Duct stones (choledocholithiasis) • Increased risk of: • cholangitis • pancreatitis • biliary obstruction
Treatment of CBD stones Endoscopic sphincterotomy (ES) If concomitant gallstones: Laparoscopic cholecystectomy 48 hours later
Endoscopic sphincterotomy • Procedure: • Cannulate CBD with sphincterotome • Cut Sphincter of Oddi • Remove stones with basket or balloon • If extraction fails use lithotripsy: mechanical, extracorporeal shock wave, laser, electrohydraulic, chemical
ERCP and ES • Stone impacted in mid bile duct. • Mechanical lithotripsy after sphincterotomy. • Completion cholangiogram after stone extraction
ES Basket extraction of multiple bile duct stones after endoscopic sphincterotomy.
Endoscopic sphincterotomy • Complication rate 5 – 10 % • Pancreatitis • Bleeding • Cholangitis • Retroperitoneal perforation • Mortality 0 - 0.4 % • NEJM 1996;335:909 (2400 patients – 17 sites) • Ann Surg 1998;201-4 (1900 patients – 7 sites)
Summary • CBD stones are fairly common • Suspect if symptoms of biliary obstruction and/or abnormal Bili/transaminases and/or abnormal US • Diagnose with MRCP or ERCP • Treat with endoscopic sphincterotomy
